Similarities and Dichotomies Between Nature-Based Solutions and Green Infrastructure: a Systematic Literature Review

Objective: The study seeks to address the following question: What are the similarities and dichotomies between green infrastructure (GI) and nature-based solutions (NBS) from the perspective of Brazilian researchers, and how do the identified solutions mitigate the depletion of urban ecosystem services? Method: A Systematic Literature Review (SLR) was conducted using the PRISMA protocol in research within the CAPES Journal database. The inclusion and exclusion criteria were original texts, peer-reviewed, published in national and international journals in Portuguese, covering the themes of NBS, GI, informal settlements, and public open space. After reviewing the 90 identified texts, a final selection of 41 texts was made for the SLR. Originality/Value: These texts were analyzed from a novel perspective, bringing together the themes of GI, NBS, ecosystem services protection, and urban land use. Results and Discussion: The study identified the authors’ views on the pressures of urbanization on ecosystem services and the solutions for their protection. It was concluded that the concepts of NBS and GI are often conflated in most approaches and that adopting urbanization associated with nature faces conceptual, operational, and managerial challenges. Research Implications: The research provides insights into the integration of GI and NBS in urban planning to address the challenges of uncontrolled urbanization and the degradation of ecosystem services.

Assessment and Dynamic Prediction of Green Space Ecological Service Value in Guangzhou City, China

As an important part of the urban ecosystem, urban green space provides a variety of ecosystem services, including climate regulation, soil conservation, carbon sink and oxygen release, and biodiversity protection. However, existing remote sensing evaluation methods for ecological service value lack the evaluation indicators of ecosystem service value for Guangzhou, China, and the evaluation method depends on the land cover type. Based on remote sensing technology and random forest algorithm, this study addresses these gaps by integrating remote sensing technology with a random forest algorithm to enhance the accuracy and rationality of ESV assessments. Focusing on Guangzhou, China, we improved the ecological service value evaluation system and conducted dynamic predictions based on land-use change scenarios. Our results indicate that the total ESV of Guangzhou’s green space was USD 7.323 billion in 2020, with a projected decline to USD 6.496 billion by 2030, representing a 12.37% reduction due to urbanization-driven land-use changes. This research highlights the noticeable role of green spaces in urban sustainability and provides robust, data-driven insights for policymakers to design more effective green space protection and management strategies. The improved assessment framework offers a novel approach for accurately quantifying urban ecosystem services and predicting future trends.

The Role of Green Infrastructure in Providing Urban Ecosystem Services: Insights from a Bibliometric Perspective

Urban ecosystems, and the services they provide, are a key focus of the United Nations 2030 Agenda for Sustainable Development, specifically SDG 11, which emphasizes making cities inclusive, safe, resilient, and sustainable. Green infrastructure (GI) is crucial in enhancing citizens’ quality of life and achieving this goal and it can be defined as a strategically planned network of natural and semi-natural areas designed to deliver a range of ecosystem services (ESs). These infrastructures improve ecosystem functioning, protect biodiversity, promote health, support sustainable land and water management, and boost the local green economy. This paper explores the scientific literature on GI and their ESs in cities using bibliometric science. By combining the keywords “Green Infrastructures”, “Ecosystem Services”, and “Cities” with VOSviewer software (1.6.20 version), we analyzed trends over time. Results show growing attention to these topics, emphasizing human well-being, urban resilience, and sustainability. The study also highlights that focusing exclusively on either “Green Infrastructure in Cities” or “Ecosystem Services in Cities” leads to fragmented insights. A more integrated examination of these three domains offers a holistic view and underscores the importance of considering ecosystem disservices. The study further identifies key research directions, including the need for a comprehensive evaluation of diverse GI types, especially those that are under-researched, such as green roofs, sports areas, and wetlands, and the underexplored role of cultural ecosystem services. Additionally, future research should consider both the benefits and disservices of GI to support better urban planning decisions. Finally, integrating biophysical, social, and economic values of ESs is critical for providing more holistic insights and enhancing sustainable urban development. The novelty of this paper lies in its integrated, holistic approach to examining GI and ESs in urban areas, with a focus on ecosystem disservices, insufficient attention to specific GI types, and the role of cultural ecosystem services—each contributing to the creation of more resilient and sustainable cities.

Urban Green Infrastructure and Ecosystem Service Supply: A Study Concerning the Functional Urban Area of Cagliari, Italy

Urban green infrastructure (UGI) is a network composed of natural and semi-natural areas, such as greenspaces, open areas, and water bodies, designed to enhance the provision of ecosystem services and to meet the needs and expectations of local communities. UGIs should be accessible and should improve the well-being and health of their users, protect and enhance biodiversity, and allow for the enjoyment of natural resources. The study proposes a methodological approach to defining a UGI, conceived as a network of areas connected by urban ecological corridors and suitable for providing climate regulation, flood risk mitigation, outdoor recreation, and biodiversity and habitat quality enhancement. The methodology is applied to the functional urban area (FUA) of the City of Cagliari, Italy. The analysis results show that areas with high values of climate regulation, carbon storage and sequestration, and habitat quality enhancement are particularly suitable to be part of a UGI. Although values for outdoor recreation appear to be less significant, the provision of this service is particularly relevant within the Cagliari FUA. However, areas characterized by high values of flood risk mitigation show a different behavior, which highlights how the presence of impermeable surface within urban areas is associated with a loss of patch connectivity.

Comparative Analysis of the Infrastructure of the City of Astana with a Sociological Survey of the Mental Well-Being of Citizens in the Context of the Sustainable Development of the Urban Agglomeration

Rapid urbanization entails complex problems not only in cities, but also within urban agglomerations. In modern landscape science, the greatest problems are primarily related to the ecological state of urban ecosystems. In this context, the most important task of urbanism is the interdisciplinary study of urban infrastructure in relation to the well-being of inhabitants, with a focus on the sustainable development of urban agglomerations. The aim of this study is to conduct a theoretical analysis of interdisciplinary research on the interactions between humans and the urban environment in the context of intensive urbanization, as well as to be an empirical study of the relationship between the real ecological state of the city of Astana, based on the use of geographical, environmental, cartographic, statistical, sociological, and socio-psychological research methods, aimed at identifying the mental well-being of citizens in correlation with their consumed urban ecosystem services using an associative psychological experiment, socio-psychological survey, and GIS mapping. As a result of this study, the authors have determined that the research hypothesis 1 “Spatial representations of the city’s geoecological state are interrelated with the mental well-being and satisfaction with urban ecosystem services of citizens depending on the area of residence” is confirmed. Additionally, a positive correlation has been noted among the key indicators and criteria of geoecological condition, mental well-being, and satisfaction with urban ecosystem services across different districts of the city.

Coupling coordination analysis and spatiotemporal heterogeneity between urban land green use efficiency and ecosystem services in Yangtze River Economic Belt, China

Rapid urbanization has resulted in the conversion of different land types, leading to a serious disruption of the balance of ecosystems, and the contradiction between land use and ecological security becomes increasingly severe. As a key factor affecting ecosystem services (ESs), improving the urban land green use efficiency (ULGUE) can effectively mitigate the decline in the ecosystem services function. This study tried to verify the profound impact of land use on ESs by measuring the coupling coordination degree (CCD) between ULGUE and ESs from the perspective of coupling coordination. However, the traditional CCD model suffers from volatility and non-comparable confidence levels in results. For this background, this study adopted the improved CCD model to measure the association between ULGUE and ESs in the Yangtze River Economic Belt (YREB). Also, a comprehensive spatial evolution of the CCD was further explored. The main conclusions are as follows: (a) The overall level of ULGUE in YREB showed an increasing trend with the distribution of ULGUE in most cities ranging from 0.71 to 1.00, showing a higher level overall and the spatial distribution character of “small aggregation, large distribution”; (b) The ESs of YREB from 2005 to 2020 demonstrated a decreasing trend and majority of cities’ current ecological protection efforts are lagging behind the extent of ecosystem damage caused by human activities; (c) The overall average CCD of YREB was largely at basically balanced level and the average CCD change ranges from 0.38 to 0.45 between 2005 and 2020, but the overall CCD had a strong spatial correlation strength. (4) To some extent, the improved CCD model solved the problems of volatility and credibility based on the traditional CCD results, which have strong rationality and scientific validity. Identifying the coupling and coordination characteristics and mechanisms can effectively provide theoretical support for the sustainable development of watersheds.

Urban forest cover and ecosystem service response to fire varies across California communities

Urban fires that result from wildfires are an emerging, extreme event affecting communities and urban forests globally. However, much of the fire effects on urban ecosystems literature is primarily focused on Wildland-Urban Interface (WUI) areas, correlates of building loss, risk mitigation, and wildland vegetation and fuels. Three recent urban fires in California USA provided an opportunity to explore these effects on urban forests: the 2017 Tubbs (Santa Rosa) and Thomas (Ventura) and the 2018 Camp fire that burned Paradise. Accordingly, we analyzed pre- and post-fire neighborhood level urban tree cover (nUTC) change over 5 years using Sentinel and LiDAR data (10m resolution). Then, we explored the effects of fire severity on changes in several regulating ecosystem services (e.g., carbon, air pollution, stormwater). Findings from the Rapid Assessment of Vegetation Condition after Wildfire severity processes and other geospatial datasets show that fire effects were patchy with fire severity within neighborhoods ranging from unburned to extreme. We found that ~5 years after the fires, and relative to adjacent non-fire affected neighborhoods, Ventura and Santa Rosa’s nUTC is recovering to pre-fire levels while Paradise’s nUTC is being consistently lost over time. Ventura and Santa Rosa had 20-25% of their fire affected area outside established WUI boundaries. However, local-scale urban tree cover and ecosystem service supply are lagged, and recovery time depends on the surrounding biome and socio-ecological context. In inland, higher elevation communities – like Paradise – the recovery of nUTC and the associated ecosystem services might materialize over a much longer timeframe. Our study provides a roadmap to assess the response of urban wildfire-affected tree cover and ecosystem services across space and time. It is also one of the first assessments of fire effects on urban ecosystems and communities outside of WUI boundaries that are now experiencing increased threat from wildfires globally.

Differential effects of urbanization-induced heavy metal pollution on soil microbial communities under evergreen and deciduous trees

Urbanization has significantly increased heavy metal contamination in urban soils, adversely affecting soil microorganisms, which are vital indicators of soil quality. However, the effects of urbanization-induced metal pollution on soil microbial communities remains largely underestimated. This study examines soil microbial communities and properties beneath the canopy of three deciduous and three evergreen trees in urban parks, situated at varying distances from the city center. The results demonstrated that urbanization consistently alters soil physicochemical properties, including pH, soil moisture, and specific heavy metal contents (e.g., Zn, Mn, Cr). The α-diversity of soil bacterial community was significantly influenced by pH and specific heavy metals (e.g., Cr, Cd), whereas the α-diversity of fungal community was affected by pH, independent of heavy metal concentrations. The response of heavy metal content to urbanization exhibited a consistent pattern across both deciduous and evergreen trees, although the effect differed between these tree types. Furthermore, urbanization impacts the diversity, structure, composition and network of soil microbial communities. Notably, the Shannon index of soil fungal communities under deciduous species shows an initial increase, followed by a decline as urbanization intensifies. In contrast, the Simpson index of soil bacteria under evergreen tree species decreases with increased urbanization. Moreover, urbanization alters soil bacterial networks, with higher network density observed in less urbanized areas. It may also affect microbial functions, such as xenobiotic and lipid metabolism. This study provided a theoretical basis for urban park soil management, which is crucial for enhancing urban soil ecosystem services and mitigating the adverse effects of urbanization.

Plant native: comparing biodiversity benefits, ecosystem services provisioning, and plant performance of native and non-native plants in urban horticulture

AbstractPlant species used in urban horticulture are frequently non-native despite evidence that urban areas are regular points of introduction, often leading to invasions and negative impacts on biodiversity. Many horticulturalists assert that non-native plants are more successful and provide equal or greater habitat and ecosystem services than native plants. However, little research has compared native and non-native plants in urban systems. We present here a systematic literature review, using the PRISMA methodology, to assess three questions: (1) Is there a difference between native and non-native plants in their ability to support faunal biodiversity in urban green spaces? (2) Is there a difference between native and non-native plants in their provisioning of urban ecosystem services? 3)Do non-native species outperform natives in urban environments in terms of survival, growth, and fitness? We extracted data from 165 total papers. One hundred and twenty studies found that native plants outperform non-native plants on the response metric evaluated in the study, 57 demonstrated mixed impacts, 56 demonstrated no differences among plant origin, and 26 found non-native plants outperformed native plants. We found overwhelming evidence that native plants support higher faunal abundance and diversity than non-native plants in urban landscapes. Relatively few studies examined ecosystem services and plant performance, but we found that native plants support higher levels and diversity of ecosystem services and that many native plants can be used for horticulture, that is, they will survive and thrive in urban conditions. Native plants provide multiple ecosystem functions in urban greenspaces, supporting urban biodiversity and provisioning ecosystem services than non-native plant species and should be prioritized in urban horticulture activities.

Residents’ Perceptions of Urban Greenspace in a Shrinking City: Ecosystem Services and Environmental Justice

Although urban greenspace enhances ecological functioning and human well-being through ecosystem services (ES), it is oftentimes inequitably distributed. Environmental justice (EJ) encompasses aspects of distributive, procedural, and interactive justice related to accessibility and allocation of environmental benefits. Vacant land in shrinking cities has the potential to address greenspace inequalities and provide ES. This study investigated the perceptions of residents regarding urban ES and EJ in their communities in St. Louis (MO, USA)—a shrinking city that was undergoing green development, through semi-structured interviews. Altogether, 27 residents were selected from socio-economically disadvantaged neighborhoods characterized by high levels of vacancy due to legacies of redlining and systemic racism. Interview analysis revealed four themes: green benefits (including recreation opportunities), green costs (e.g., concerns for increased crime and nuisance animals), injustice issues (e.g., access to community greenspaces), and changes in the community (e.g., higher property taxes). Results revealed that residents perceived ES as closely connected with EJ when it comes to urban greening projects in their city. This study helps inform the process of urban greening projects, particularly in shrinking cities at risk of inequities.

Assessing variation in the perception of urban ecosystem services at the sub-city level

ABSTRACT Assessing residents’ perceptions of urban ecosystem services (UESs) is crucial for incorporating it into environmental management. However, evaluations seldom consider variations in perceptions at sub-city scale. Our study demonstrates how UES perceptions varies at sub-city level through a case study in Beijing, China. We interviewed 550 residents of Beijing’s oldest and newest urban zones to obtain their perceptions of 10 UES types. We analysed participants’ responses using importance-performance analysis, optimal scale regression, and textual analysis. Results showed that residents confirmed the value of UES in both zones. However, differences existed in their perceptions of several UESs, reflecting different environmental problems between two zones. Additionally, education, gender, and age significantly affected residents’ perceptions. Residents in both zones prioritised greenery-expanding activities for improving UES performance. Based on these findings, we recommend that variances in UES perception be considered when managing urban ecosystems to improve its supply and contribute to human well-being.

Ecosystem Services and Public Perception of Green Infrastructure from the Perspective of Urban Parks: A Case Study of Luoyang City, China

As one form of urban green infrastructure, city parks provide essential ecosystem services and serve as a vital link connecting citizens with natural ecosystems. The public, as the primary beneficiaries of urban park ecosystem services, plays a crucial role in guiding the improvement and development trends of urban park planning. Most existing studies assess the comprehensive value of green spaces from a macro scale, with few focusing on the cultural and regulatory ecosystem services of urban parks and public perception of these services at the park level. This study targets 11 typical urban parks in Luoyang City, collecting 771 samples through field mapping and surveys. It analyzes users’ socio-demographic characteristics, perception abilities, usage preferences, and service satisfaction, linking these subjective factors with objective elements of the park environment, such as fitness and recreational facilities. The results indicate that respondents with knowledge of ecosystem services are better able to evaluate and understand services such as air pollution reduction and noise reduction in parks, while those without such knowledge tend to focus more on services that they can intuitively perceive, such as biodiversity conservation and microclimate regulation. Additionally, the middle-income group exhibits a higher level of awareness of park ecosystem services, which depends on their active social participation. The findings of this study suggest that enhancing public understanding of ecosystem services through environmental education is key to improving the quality of urban ecosystems.

Mega project impact on urban growth and ecosystem service

In an effort to forecast and estimate the value of ecosystem services (ESVs) and land use and land cover changes (LULC), recent global events and research have centered on the evaluation of LULC. This study evaluates the effectiveness of an integrated approach using multi-layer perceptron-Markov chain analysis (MLP-MCA) and remote sensing data for monitoring land use and land cover (LULC) changes. The study area comprises the three Bangladeshi upazilas that the Padma Bridge connects: Shariatpur, Louhajang, and Janjira. The Ecosystem Services Valuation Database (ESVD) was used to evaluate the impacts of changes in land use and land cover (LULC) on Ecosystem Service Values (ESVs). The LULC of the study area was estimated for the years 2000, 2010, and 2020, and the forecast period for urban development was 2030 and 2040. Additionally, the monetary value of ecosystem services was evaluated across the time. As per the LULC change analysis, there is a projected 4.35% growth in the built-up area from 2000 to 2020. After the bridge is constructed, the built-up area is projected to increase by 7% in 2030 and 14% in 2040, according to the forecast. The exponential expansion of developed land has a paradoxical effect on the value of ecosystem services. From 2020 to 2040, it is expected that the ESVs for provision, regulation, culture, and support will experience a reduction of approximately 213.24 million USD/ha. Even if the establishment of a bridge results in economic stability and investment attraction for the nation, unforeseen ecosystem service losses cannot contribute to long-term, sustainable development. This study, by establishing a correlation between urban area expansion and the deterioration of ecosystem services, can serve as a standard and basis for guiding management decisions.

Research on Plant Landscape in Urban Wilderness Space: A Case Study of Jiangyangfan Ecological Park in Hangzhou

In recent years, with the acceleration of urbanization, the construction and management of urban wilderness space has become an important research field. The study of plantscape in urban wilderness space is one of the key points. Plant landscape is the core element of urban wilderness space, which plays an important role in improving urban environment and ecosystem service function. In this study, we chose Hangzhou Jiangyangfan Ecological Park as an example, and identified two main areas, the habitat island and the lake area, to be used as the research sites for plant species. The distribution of plant species, community structure, seasonal variation and spatial characteristics of these areas were studied and evaluated in detail. Based on the actual data collection, we will propose the following plant construction strategies: introduction of native species, creation of communities close to nature, use of temporal characteristics of plants, and the use of plants to shape the aesthetics of horticultural spaces.

Impacts of soil de-sealing practices on urban land-uses, soil functions and ecosystem services in French cities

Soil sealing has been recognised as one of the main causes of urban soil degradation in Europe. To tackle this issue, de-sealing measures have recently been promoted in cities to increase the sustainability of soil ecosystem services. To our knowledge, very few evaluations of de-sealing projects have as yet been done to assess the current framework of these urban planning practices. Therefore, we conducted an online survey to collect and analyse soil de-sealing projects throughout mainland France. A 60-question survey was run over a 4-month-period, and data about 57 projects were collected. The answers covered a diversity of projects, structures and stakeholders and included data such as the location / objectives / costs and benefits of the projects implemented in cities of various sizes. A typology of urban land-uses before and after de-sealing was defined. Among the diverse objectives of de-sealing, rainwater management, reducing urban heat, and greening were most frequent. More than half of the respondents (64%) indicated that ecosystem services were used to drive their de-sealing project. The methods usually required excavation of the sealing cover and road layers being replaced by newly imported fertile materials. Recent de-sealing projects have reused derelict materials from the site (soil-material inventory) and/or local urban waste for soil construction, which can help minimise both the economic and environmental costs of urban greening projects. The results of this study provide quite an exhaustive view of current French de-sealing practices and could provide guidelines for improving soil functions by applying soil engineering processes to construct sustainable fertile soils for urban greening.

Urban sustainable development goals and ecosystem services: Pathways to achieving coordination

It has been widely recognized that progress toward achieving Sustainable Development Goals (SDGs) must be better harmonized with Ecosystem Services (ESs) to tackle global challenges. In China, the National Key Ecological Function Areas (NKEFAs) were set up as one of the ecological fiscal transfer projects. Despite its significant influences on the SDGs-ESs nexus, there is a lack of empirical studies on the effects and mechanisms of policy. In response, this study provides a synthesized framework that incorporates the coupling coordination degree between the Urban Sustainable Development Goals (USDGs) and Ecosystem Services Scores (ESSs), empirically verifies the policy effect using the difference-in-differences model, and then further investigates the mechanisms of government action to coordinate urban SDGs and ESs. The results show that: (1) The coupling coordination degree between USDGs and ESSs varies significantly across different regions but steadily increases over time, with a faster increasing rate of coordination degree growth in NKEEFAs pilot cities compared to non-pilot cities. (2) The policy has demonstrated benefits in coordinating USDGs and ESSs with a coefficient of 0.005. In detail, the policy enhances ESSs but concurrently exerts a negative influence on USDGs, with coefficients are 0.008 and −0.004 respectively, suggesting an uneven distribution of the policy's impacts. (3) The study unveils the 'technological innovation effect' and the 'industrial agglomeration effect' as crucial mediating pathways for policy effect, laying a solid foundation for USDGs and ESSs coordination. In total, the study highlights the critical need to account for regional development disparities and adequate funding in ecological protection policies to ensure fairness and effectiveness from a central decision-making standpoint. It recommends enhancing transparency in fiscal expenditures and fostering regional joint coordination to address local government challenges. These insights from this study can offer valuable guidance for policymakers to refine policy implementation and promote the coordination of regional ESs and SDGs.

Effects of growth space limitation on allometry of Ficus spp. In urban habitats

Tree morphological traits are related to the structural stability and their ability to provide ecological benefits such as carbon sequestration and water conservation. The allometric relationship can be used to construct the corresponding prediction equations in forests. However, the urban environment differs from the natural environment for trees. This study aims to enhance the urban tree growth model by classifying urban habitats. We achieved this by collecting morphological traits (DBH, height, crown depth, and width) commonly used in growth model researches of six Ficus spp. in Guangzhou, China, including Ficus virens, Ficus religiosa, Ficus elastica, Ficus benjamina, Ficus altissima, Ficus celebensis. We specifically examine how these trees grow in different urban settings. Urban habitats are classified based on growth space limitations, considering above-ground and underground. Results showed that certain morphologies in urban habitats did not conform to allometry (R2 < 0.4), and the model fitted with height as independent variable is better than that fitted with DBH. The model parameter following allometric relationship with tree height as the independent variable showed no significant difference, but the fit was worse in different urban habitats. On the contrary, models with DBH as the independent variable showed differences, for example, the allometric exponent of maximum crown width relative to DBH were 0.915 and 0.557 in two different habitats. Crown depth and tree height showed significant and stable allometry in the three habitats. The response of tree morphology to different habitats varied, and the allometric relationships among morphological traits showed differences in habitats where the growth space was limited. This underscores the considerable effect of the urban environment on urban tree growth models. Consequently, we recommend developing a series urban tree growth models tailored to different urban habitats to accurately quantify urban ecosystem services for assessing their sustainability in urban development and planning.
